OpenSSL up to 0.9.x cryptographic issue

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Summaryinfo

A vulnerability marked as problematic has been reported in OpenSSL up to 0.9.x. Affected is an unknown function. Performing a manipulation results in cryptographic issue. This vulnerability is known as CVE-2011-4354. No exploit is available. It is suggested to upgrade the affected component.

Detailsinfo

A vulnerability, which was classified as critical, was found in OpenSSL up to 0.9.x (Network Encryption Software). This affects an unknown code. The manipulation with an unknown input leads to a cryptographic issue vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:

crypto/bn/bn_nist.c in OpenSSL before 0.9.8h on 32-bit platforms, as used in stunnel and other products, in certain circumstances involving ECDH or ECDHE cipher suites, uses an incorrect modular reduction algorithm in its implementation of the P-256 and P-384 NIST elliptic curves, which allows remote attackers to obtain the private key of a TLS server via multiple handshake attempts.

The weakness was published 01/26/2012 as Bug 757909 as not defined bug report (Bugzilla). It is possible to read the advisory at bugzilla.redhat.com. This vulnerability is uniquely identified as CVE-2011-4354 since 11/04/2011. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1600 according to MITRE ATT&CK.

The vulnerability scanner Nessus provides a plugin with the ID 57543 (Debian DSA-2390-1 : openssl - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 195118 (Ubuntu Security Notification for Openssl Vulnerabilities (USN-1357-1)).

Upgrading to version 0.9.7e eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (71601), Tenable (57543), SecurityFocus (BID 50882†) and Vulnerability Center (SBV-40300†). Be aware that VulDB is the high quality source for vulnerability data.
